Specification of Letters Patent.

To all wiz/omit may concern:

vBe it known that I, LoUIsLSrooKsTRoiyr, a citizen of the United States, residing at St. Louis, in theState of Missouri, haveinvented certain new and useful Improvevments in Oil-Stove Tick-Tubes, ofiwhich the following is a specification, reference being had `therein to the accompanying drawing. f

This invention relates to improvements in oil stove wick tubes, and is particularly intended for use in blue-flame wick stoves, of that type which utilizes inner and outer air distributers and an elongated imperforate chimney, the lower end of which embraces the outer air distributer.

The primary object of my invention is to so construct the wick receiving tubes that while the wick snugly fits between the tubes, at the same time friction is reduced so that it will move freely between the wick tubes and insure an even upward adjustment thereof throughout the circumference of the wick. i

In the type of blue-,name stove, above referred to, it is essential that the wick project uniformly above the upper ends of the wick tubes, and in order to insure this result it is necessary that the wick move upward uniformly throughout its circumference. Y

My improvement furthermore provides spaces in which foreign matter may collect, instead of accumulating between the engaging surfaces of the wick and the wick tube, and also prevents theV wick from sticking between the tubes whenv it is necessary to remove it, and also assists in enabling a new wick to bel more readily placed in position between the tubes.

In the drawings- Figure l is a vertical central sectional view taken through the wick tubes embodying my present improvement.

Fig. 2 is an enlarged segmental combined horizontal and vertical sectional view embodying my present improvement.

Fig. 8, is a fragmental vertical sectional view, showing the wick adjusting wheel.

In carrying out my invention, there is an outer tube l and an inner wick tube 2. My present improvement consists in providing one of these wick tubes with longitudr nal corrugations. Preferably, these corrugations 3 are formed in the inner wick tube 2. The lcorrugations extend' longitudinal 'of the inner wick tube, as shown, and: their Patented. Fenna, v192.1.

upper ends-4v stop at a pointl below the upper end .5 of the inner :wick tube, whichy leaves a straight wall portion .6, at the upper end ofthe inner wick tube.: rlhis straight wall .l

portion 6 is parallel with the wall of theY outer wick `tube l, and this construction leaves the upper ends of the inner and outer wick tubes unchanged in form.

This construction reduces the friction of the wick 7 between the inner and outer wick tubes approximatelythroughout the length of the wick, which enables it to move freely between the wick tubes without anyy tendency to stick at any one point, and removes the frequent tendency of wicks to lag behind at some point throughout its circumference, which lagging will cause an uneven projection of the upper end of the wick at the upper ends ofthe wick tubes. F urthermore, the corrugations form spacesV or pockets 8 into which foreign matter will collect instead of between the wick and wick-tube, thus relieving sticking and uneven movement being caused by the accumulation of foreign matter between the wick and wick-tube. Again, the corrugations stiifen the inner wick tube` which is made of thin metal and this stiifening of thel wick tube assists in preventing the inward spring-v ing of the tube under the pressure of the wick lifting wheel 9. Y j Y The inner tube 2 is further stiffened by one or'more annular rings 10 and 11, which, as here shown, are L-shaped in cross-section and suitably secured within the corrugated portion of the inner wick tube 2. The stiii'ening ring 11 and the wick adjusting wheel 9 are located substantially in the same horizontal'plane, and the ringstifl'ens 'the inner wick tube at thispoint to prevent any inward springing thereof under pressure of the adjusting wheel 9, which obviates the not unusual disengagement of the wheel with the perforated wick band 13.

I do not wish to limit myself to the particular` form of corrugations here shown, nor to have them extend in longitudinal alineme'nt with the wick tube, as hereV shown, as this arrangement might be varied and still embody some, if not all, the advantages of the specific construction here shown.

While I prefer to have the inner wick tube provided with corrugations to accomplish the result herein described, I do not desire to limit myself in that respect. Nor do I desire'to limit myself to having the corrugations in only one of the wick tubes.

Having thus described my invention, what I claim and desire to secure by Letters Patent is Y I l. In a wick burner,`inner and outer wick tubes, a wick between the tubes and resting against the outer wick tube, the inner wick tube 'having inwardl extending longitudil nal vcorrugations beginning at points below the upper end of the inner wick tube, whereby theupper end of the wick is in engagement with the upper ends of both the inner and outer wick tubes, the inwardly extendy described.

2. A wick tube cor'istructi'on comprising inner and outer wick tubes, the inner wick o tube having longitudinal corrugations, a strengthening ring secured within the inner corrugated portion of the inner tube, a .wick between the tubes carrying a wick elevating sleeve and a wick adjusting wheel carried by the outer wick tubeand engaging the sleeve in approximately the horizontal plane of 'the strengthening ring.

In testimony whereof I signature.
